Thank you for viewing. Used item. The pistons and slides are not stuck, and all parts function well. The inside of the tubes has been cleaned, basic operation has been confirmed, and a simple play test has been performed, so you can start playing immediately. In my subjective opinion, the exterior has a well-worn feel, and the polished brass shines with a profound presence. 【Important】 It has been unlacquered, so the current color is the natural brass color. This is recommended for those who enjoy the aging process through oxidation or who want to apply their own bluing treatment. Also, the oxidation film can be easily restored to its original shine by polishing with products like Piccard. ■ The appeal of unlacquered (ChatGPT) ① The sound of brass itself, which cannot be experienced with plating or lacquer. The tone is soft and tends to be rounder than with lacquer. ② The unique vintage feel that changes with the oxidation film as you use it is attractive. You can easily restore the original shine by polishing with Piccard liquid. ③ A unique tone with a strong presence in jazz and solo performances. ■ About YTR-2321 (ChatGPT) Manufactured in Japan (Hamamatsu factory, etc.) from the 1980s to the early 1990s.
